.DIE FOR. MANUFACTURE oF MoLDsD ARTICLES.

SPECIFICATION forming part of Letters Patent No. 537,187, dated Apri1-9,1895. Application sled Aprnl, 1892. seria No. 427,319. (ne moan.)

new and useful Improvements in Dies for the Manufacture of MoldedArticles, of which the following is a specification, reference being hadtherein to the accompanying drawings.

In the manufacture of molded articles, as brush and mirror backs, paperWeights and the like, which are made from plastic composition which ismolded to shape in dies, it is often desirable to provide the articlewhich is molded 'with a panel or piece of material which is of adifferent character for the purpose either of producing an ornamentaleffect, or for reducing the cost of the article by replacing a part ofthe composition employed by the material of the panel and which may beless expensive than the plastic composition or for the purposes ofadvertising or the like. Some of these objects are ineflicientlyattained by securing, by the use of adhesive material, a piece of paperor similar thin layer to the surface of the article which is molded.This does not attain the object desired and does not aord, so far asknown to me, a neat, durable and desirable panel. It is also deemedobjectionable to secure a panel by means of pins or similar devicesinasmuch as the face of the panel is injured or marred by the use ofsuch devices, and at the same time it is desirable that the panel shouldbe properly centered in that part of the article which is designed toreceive it. I

My invention has for its object to obviate the difficulties encounteredin the manufacture 'of such articles made from plastic composition, andto provide a die by the employment of which a molded article which shallbe free from the above defects may be made, and it consists in a dieprovided with a space,

, corresponding in size and shape to the panel,

which is to be inserted in the article, the walls of the die adjacentthe said space being made flaring or beveling all as hereinafter setforth.

In the drawings accompanying this speciflcation, I have shown at Figure1 a plan view of a brush back havinga panel securedthereto. Fig. 2 is asection on line 2-2 Fig. 1.

Fig. 3 is a similar section of the metal'die in which the brush back ismolded showing the composition and the panel in place therein. Figs. 4and 5 are enlarged details, broken away, showing dies of differentforms.

A represents a die, the concavity in which corresponds to the shape ofthe article which is to be molded. The portion of the die which isdesigned to receive the panel is shown at a and this portion vshouldcorrespond accurately in size and shape with the panel which is to beinserted in, or secured to, the article. The panel is shown at d.v Thepanel is preferablyr of substantial thickness in order that it may befirmly held by the composition, lo. The sides or walls f of the dieadjacent the part o. thereof, are inclined, or made beveling, so thatany horizontal section of the cavity of the die above the bottom orportion a thereof will be larger in area than said portion a. Thisconstruction of the die permits the plastic composition 7o to flow, orbe pressed, into the space between the edge of the panel and the flaringsides or wallsfso that in the molded article the panel will be protectedaround its edge, and up to its exposed surface, by the composition,while at the same time, since the panel d fits the bottom portion o. ofthe die, it will not be displaced when the composition ispressed intothe die. These features of the die will be clear upon reference to Figs.4t and 5 of the drawings.

If the flat bottom dof the die were largerl than the panel the placingof the composition in the die, and the pressure applied thereto,

would be apt to displace the panel and in the finished article the panelwould not be in its proper position, but would be out of the center ofthe space which it is designed to occupy. As will be clear the essentialfeatures of the die are the portion a, corresponding in size to thepanel to be used, and the beveling or inclined side-walls f adjacent thesaid portion a. By the employment of a die of this construction, amolded article may be provided with a panel which may be accuratelyplaced in the article without the use of securing pins, or similardevices, which mar or puncture the face of the panel. A panel may beemployed of relatively great thickness, the con- IOO sion inclined or`beveled outward for the re x5 ception of a portion of the plasticmaterial around the edges only of the panel, said walls or sidesconstituting shoulders around the depression to engage with the edges ofthe panel and thereby fix the latter in precise pozo sition,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
